Overview of this book

openFrameworks is a powerful programming toolkit and library designed to assist the creative process through simplicity and intuitiveness. It's a very handy software library written in C++ to reduce the software development process, helping you to kick-start creative coding. With the help of C++ and shaders support, openFrameworks allows for the processing of all kinds of media information with your custom-developed algorithms at the lowest possible level, with the fastest speed. "Mastering openFrameworks: Creative Coding Demystified" will introduce you to a world of creative coding projects, including interactive installations, audio-visual, and sound art projects. You will learn how to make your own projects using openFrameworks. This book focuses on low-level data processing, which allows you to create really unique and cutting-edge installations and projects. "Mastering openFrameworks: Creative Coding Demystified" provides a complete introduction to openFrameworks, including installation, core capabilities, and addons. Advanced topics like shaders, computer vision, and depth cameras are also covered. We start off by discussing the basic topics such as image and video loading, rendering and processing, playing sound samples, and synthesizing new sounds. We then move on to cover 3D graphics, computer vision, and depth cameras. You will also learn a number of advanced topics such as video mapping, interactive floors and walls, video morphing, networking, and using geometry shaders. You will learn everything you need to know in order to create your own projects; create projects of all levels, ranging from simple creative-code experiments, to big interactive systems consisting of a number of computers, depth cameras, and projectors.

ofxOpenNI examples

The addon includes a number of examples, exploring basic depth camera and OpenNI capabilities. The examples are short, self-explanatory, and well commented. There are three groups of examples: working with depth images, tracking hands, and tracking users. Let's discuss them.


Currently, the ofxOpenNI addon holds examples in an "almost ready form". You need to construct the desired example by copying the source files and libraries in one folder. It's not very comfortable but is quite simple. Please see the Drivers & getting the examples to work section of the README file inside the addon's folder for details.

When you compile an ofxOpenNI example under Mac OS X for the first time, you can get the following compiler error:

The specified SDK "Current OS X" does not appear to have all of the necessary headers installed...

To fix the error, you need to install the Command Line Tools package in Xcode. Namely, go to the Xcode menu, click on Preferences..., and go to the Downloads...
